Make auto generation of local vars in Dart configurable / IntelliJ / Dart Analysis Server protocol

[MikeMitterer]

class MySimpleClass {
   // whatever
}

void mySimpleFunction() {
    new MySimpleClass();
}

If I click on "autogenerate local variable" in IntelliJ it gives me:

var xyz = new MySimpleClass();

I hate that! Autocompletion of vars in Dart is useless for me.
I don't want a var I want final MySimpleClass xyz. Please make this configurable. The Dart-styleguide should help - not dictate.

var without Type-Information: THIS IS NOT A GOOD PROGRAMMING-STYLE.
